<div class="textblock"><p>This class can be used to find points and features in pictures using SIFT detector. </p>
<p>To create a structure from motion, most methods use points to compute the structure. This class focus on the first task in SfM: find points in image which are easy to track... When available, a feature vector for each points is very helpful: the matching will be easier. </p>
